ROVlNG-GUIDE.

SPECIFIGATION forming part of Letters Patent No. 707,874, dated August26, 1902.

Application filed January 14, 1902. Serial No. 89,745. (No model.)

To CLZZ whom, it may concern.-

Be it known that I, FREDERICK STEvENsa citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Roving-Guides for Textile Machinery, of which thefollowing is a specification.

My invention relates to certain improvements in guides for directingwoolenrovings IO as these latter pass from rubbing-rolls to themechanism for winding them upon bobbins.

The object of my invention is to provide a device which shall keep tworovings separate from each other while guiding them close together upona bobbin, at the same time giving them a false twist, by this meanspreventing what is known as robbing. This object I attain as hereinafterset forth, refer.-

ence being had to the accompanying drawings, in which Figure 1 is aninverted perspective view of my improved guide, showing two strands orrovings passing therethrough on their way to the bobbins; and Fig. 2 isa side view of the same. A

It is customary in the art to provide a sin gle conical or funnel shapedguide to direct a pair of rovings as they pass to the winding mechanism.The rovings both enter the taporing cavity in the guide and are more orless pressed together and condensed by the time they reach the end ofthe same and emerge therefrom. Such pressing together causes the fibersof wool of each strand toin- 5 tertwine, to a greaterorless extent, withthose of the other, so that when the double strand is unwound from abobbin one of its constituent strands almost invariably draws somefibers from the other. This action is known as robbing and results instrands which are of varying diameter, lessening in value any finishedarticle made from such strands.

By my invention I am enabled in a great measure, if not altogether, toovercome this objectionable action, and in applying the same I prefer toconstruct my device in the form shown in the drawings.

A is the L-shaped body of the guide, one

portion A being secured to a support. In

the present instance this portion A has an opening a for the passage ofa securing-bolt c, Fig. 2. If desired, the sides of this plate may bemade plain, as shown at a, so that the portion A may enter a rectangularrecess in the supporting-frame, by means of which greater rigidity ofthe guide is secured. The body portion A of theL-shaped guide is madewith an opening a from the forward end of which extend two parallel andpreferably cylindrical guide-passages a open on the under side.

Projecting from each side of the guide A, in the line of/junction of thetwo portions thereof, are ,bars or, preferably circular in section andformed integral with the guidepiece prope in the present instance.

As shown in the drawings, the edges of the sides of the opening a arerounded, as are also the outside edges of the guide adjacent tosaid'opening. 7o

In operation one of the rovings is passed under the bar at, thenupwardly over the side a of the horizontal plate and into the opening afinally entering the adjacent guidepassage a The second roving b issimilarly passed under the second projecting bar ct, over the side a ofthe plate, and into the sec ond passage a It will be seen that as therovings are pulled through this guide they are given a half-turn, thisbeing known as a false twist. As will be understood by those skilled 'inthe art, the fibers or rovings as they come from the rubbing-machine arenot twisted, and it will be noted that by thus giving'the roving ahalf-twist as it passes through the guide. the tendency of the fibers toseparate is to some extent overcome. Again, it is to be noted that bypassing the two strands out of the guide through separate passages andnot 0 pressing them together the tendency of the fibers of one strand tointerlock with those of the other is to a great extent avoided. Thiscondition, taken in connection with the false twist given the strand,most effectually pre- 5 vents the robbing, which has heretofore givenconsiderable trouble.

I claim as my invention 1. A guide for woolen rovings comprising a bodyportion having an opening provided with a passage or passages extendingtherefrom, with means other than said passages for imparting a falsetwist to strands of material passing through the same, substantially asdescribed.

2. A guide for woolen rovings comprising a body portion having anopening and a plurality of substantially straight passages extendingfrom said opening, with means other than said passages for imparting afalse twist to strands of material passing through the same,substantially as described.

3. A guide for woolen rovings comprising a body portion, having anopening and a plurality of passages extending from said opening, withprojections on the body portion whereby a false twist is given tostrands of material prior to their entrance into said pas sages,substantially as described.

4. A guide for woolen rovings comprising two portions joined together,one portion having through it an opening, and a plurality of ing throughit an opening and a plurality of passages extending from said opening,the other portion having an opening for the passage of a securingdevice, and projections formed integral with the guide and extending ina plane substantially parallel to one of the portions thereof,substantially as described.

6. A guide for woolen rovings comprising two portions joined togetheralong one edge, an opening through one of the portions, two passagesextending from one side of said opening to the end of the guide and twosubstan- FREDERICK STEVENS.
